How can I check if my estimated Max HR Is correct?

You can determine if your estimated MHR is correct by comparing Myzone effort zones to your rate of perceived exertion (RPE) during cardiorespiratory exercise. That last part – “during cardiorespiratory exercise” – is important, because RPE doesn’t always match up with exercise intensity during muscular fitness or resistance training.

Rate of perceived exertion uses a scale of 1-10 (1 = lightest intensity, 10 = maximal intensity). For example, you should feel like you’re at about a 6 on the RPE scale when you’re exercising in the BLUE zone (60-69% of estimated MHR), and you should feel like you’re at about a 9 or 10 on the RPE scale when you’re in the RED zone (90%+ of estimated MHR).

If you’re a new Myzone user, pay attention to your Myzone effort zones and your RPE during your first few cardiorespiratory workouts. Do they align closely? Is there an obvious discrepancy?
